ACT Prolite Flywheel 600240
The ACT Prolite Flywheel 600240 is engineered for performance, featuring a lightweight design that minimizes inertia for quicker throttle response and improved acceleration. This flywheel is particularly suited for competitive environments such as road and rally racing, where every millisecond counts. While it enhances performance, it may reduce drivability for daily driving applications.
Construction and Materials
Constructed from high-quality chromoly steel, the 600240 offers exceptional strength and heat tolerance. The flywheel features a heat-treated forging process that enhances its toughness, while the induction-hardened ring gears ensure durability and longevity. The one-piece construction minimizes the risk of failure, allowing for efficient heat transfer from the clutch disc. This design eliminates issues such as warped inserts or loose ring gears that can plague multi-piece flywheels.
Performance Features
- Significantly improved engine response and acceleration.
- Produces mild to moderate gear rattle, typical in high-performance applications.
